Cooling is the fastest-growing use of energy in buildings but is also one of the most critical blind spots in today’s energy debate. Rising demand for space cooling is putting enormous strain on electricity systems in many countries, as well as driving up emissions. Comparing to heat, power, and transport, cooling had long been under-represented in the EU energy policy until 2016 when the European Commission took the first step with the launch of its Heating and Cooling Strategy. The strategy identifies actions of ‘increasing the share of renewables’ and ‘reuse of energy waste from industry’ as two key areas for decarbonizing cooling to meet the EU’s climate goals by 2050. Accordingly, the targets are only achievable with fast development and deployment of new efficient and effective cooling technologies driven by either ‘renewable electricity/heat’ or waste heat. This CO-COOL RISE project assembles an international, interdisciplinary consortium from 12 research institutions and 5 industrial companies to collectively accelerate the cooling technology development and deployment, with complementary expertise/skills including composite solids, phase change materials (PCMs), complex fluids, process intensification (heat and mass transfer), cold thermal storage, refrigeration systems, as well as techno-economic analysis (TEA) and life cycle assessment (LCA), marketing analysis, and entrepreneurship skills. Based on the innovation of composite solids (sorbents/PCMs) and fluids (PCMs and hydrate slurries) as well as related components and systems, the project aims to develop renewable/recoverable energy driven, storage-integrated cooling technologies which could offer energy resource-efficient and cost-effective solutions to meet end-users’ low carbon cooling demand.

Rapid expansion of utilisation of solar thermal energy for increasing energy efficiency of buildings have been adopted in short/medium- and long-term Energy Strategies of EU countries in line with regional actions with the European climate energy objectives as defined in the European Union’s “20-20-20” targets and in the European Commission’s Energy Roadmap 2050. The overall objective of this project is to develop an innovative high performance and cost effective 2-kWel/18-kWth solar heat and power system for application in individual dwellings and small business residential buildings for on-site electricity and heat generation using solar thermal energy at temperature levels of 250-280 deg.C. The proposed technology will be laboratory validated and undergo filed tests on a demonstration site. The project will utilise the expertise of the consortium members in the development of small Organic Rankine Cycle plants, linear Fresnel mirror solar energy concentrating collectors; advanced heat pipe technologies for the thermal management; high performance Thermal Energy Storage systems on the basis of Phase Change Materials; smart control units for integration of solar thermal and boiler heating circuits. Also participants of this Project are experienced in integration of Renewable energy technologies into buildings, optimisation of complex plants and in analysis and predictions of socio-economic impact and in commercialisation of new Renewable energy products; It is estimated that the proposed technology will deliver 60% of domestic energy requirements and provide 20% reduction in energy costs and Green House Gas (GHG) emissions compared to the best existing low carbon energy technologies. In this way the project will also assist in improving the quality of life of population within and outside the EU and provide clean, efficient and secure energy to dwellings.

The SWS-HEATING project will develop an innovative seasonal thermal energy storage (STES) unit with a novel storage material and creative configuration, i.e. a sorbent material embedded in a compact multi-modular sorption STES unit. This will allow to store and shift the harvested solar energy available abundantly during the summer to the less sunny and colder winter period thus covering a large fraction of heating and domestic hot water demand in buildings. The targeted benefit of this next generation solar heating technology is to reach and overcome a solar fraction of 60% in central/north Europe, reaching 80% in the sunnier south of Europe, with a compact and high-performing STES system at low cost, realising solar-active houses throughout EU. The SWS-heating system is based on a multi-modular sorption seasonal thermal energy storage (STES) unit, using novel sorbent materials of Selective Water Sorbents (SWS) family characterised by superior heat storage density compared to the state of the art, making it possible to drastically decrease the storage volume with negligible thermal losses. These materials are employed in a sorption module with dedicated heat exchangers. Solar heat is provided to the storage modules by high-efficiency evacuated tube solar thermal collectors. Intensive research activities will deal with an advanced vacuum combi-storage tank, with the aim to further minimise thermal losses. A smart and adaptive control will be developed for efficiently managing heat supply and demand sides, including advanced features aiming at user-friendliness. A building prototype will be commissioned including the SWS-heating system, which will be tested and validated in Germany and Sweden and proof all challenging objectives. The project also includes dissemination and communication activities to ensure outreach of its results. Moreover, exploitation activities include long-term deployment path development through a technology roadmap.

Following the EC SET-Plan Education and Training Roadmap, the concept of this proposal is to develop a joint PhD programme between universities and research centres, on the topic of Thermal Energy Storage (TES). The goal of INPATH-TES is to create a network of universities and research institutes to implement a joint PhD programme on TES technologies. The final result of such a network is to educate professionals on these technologies for the European research and industry institutions. The consortium includes 14 universities that will implement the joint PhD programme, two research institutions (AIT and PROMES-CNRS), three companies and two SME (Arcelik, Abengoa Solar NT, KIC InnoEnergy, UFP and LAIF), that will cooperate in defining the programme and in its implementation and deployment. The specific objectives of the project will lead to the qualification of professionals for the European research and industry institutions, bringing Europe to continue being leaders in these technologies. The partners in the proposal will be the core of a future larger network of excellent R&D institutions, and industries for co-funding and industrial placement, sharing infrastructure capacities, and enhancing mobility of students. The overall approach of the project involves a work plan divided in six work packages, being either coordination or support activities. Coordination activities: WP1 – Management and coordination; WP3 – Developing, maintaining and updating a PhD programme in TES; and WP4 – Implementation of the PhD programme in TES. Support activities: WP2 – External communication and dissemination; WP5 – Stakeholder involvement and extension of partnerships; and WP6 – Framework for monitoring and evaluation of INPATH-TES as well as IPR and regulatory issues.
